low-light and concealment

[ogre]

I asked this in the Modern forum and got great responses, but I'm still not sure exactly how low-light effects concealment (due to light). The 3.5 SRD doesn't even mention concealment.
So, what is the RAW for low-light negating concealment miss chances? I'm assuming darkvision negates all miss chances due to light. Does low-light only effect one-half? Does it lower nine-tenths?
Here's what I posted in the Modern forum...

How does low-light vision and darkvision for that matter effect concealment miss chances and hide skill bonuses? The description is rather vague.
Low-Light Vision (Ex): A creature with low-light vision can see twice as far as normal in poor lightning conditions. The creature can still distinguish colors, even in dim lighting.
Table: Concealment

Concealment (Example) Miss Chance
One-quarter (light fog; light foliage) 10%
One-half (shadows; dense fog at 5 ft.) 20%
Three-quarters (dense foliage) 30%
Nine-tenths (near total darkness) 40%
Total (attacker blind; total darkness; smoke grenade; dense fog at 10 ft.) 50% and must guess target's location
Helpless Defenders

Does low-light negate the miss chance altogether, lower it to a lesser grade?
What about Darkvision?

In 3.5, total concealment is 50% miss chance. Concealment is 20%. No "stages" like in 3E (which is good IMO; figuring whether something is "one-quarter" or "one-half" concealment isn't worth it).

Darkvision negates all concealment miss chances assuming the target isn't invisible/incorporeal/etc.

Low-light vision doubles the range of illumination from a light source. Eg a torch provides full illumination to a radius of 20', and shadowy illumination (concealment, 20% miss chance) for 20' beyond that. Outside the range of illumination, you get total concealment (50% miss chance). A creature with low-light vision benefits from full illumination out to 40', with shadowy illumination for another 40'.

What about Darkvision?

Darkvision completely negates darkness-based concealment within the range of the darkvision (usually 60 feet).

Low-light vision merely extends the area that you can see perfectly, and also the area you can see poorly in. For example, a torch gives bright light (no penalty) with a radius of 20 feet, with shadowy illumination out to 40 feet. An elf (who has low-light vision) would enjoy bright light out to 40 feet, and shadowy illumination out to 80 feet.

Someone could hide 30 feet away from a human with a torcch, but would not be able to hide 30 feet away from an elf with a torch (since to an elf, the bright light extends to 40 feet).
Similarly, someone hiding 60 feet away from an elf with a torch would only enjoy Concealment against that elf, rather than the Total Concealment he would enjoy against a human with a torch.

So, a low-light vision will negate concealment if the creature is within the extended bright light area, but not otherwise.

References to fractional concealment were not carried over to 3.5 from the 3.0 ruleset. It's either Concealment (20% miss chance, enjoyed by characters in shadowy illumination), and Total Concealment (50% miss chance, enjoyed by characters in full darkness).

Hope this helps.

Ahhhh, now I see why they didn't explain it further. Of course, this doesn't help with my d20 modern dilema, which still has the fractional concealment rules.
Guess I'll have to deal with it, or switch it over to 3.5.
Thanks for the help guys.
